Tower Plus

Tower Plus is a full featured networking access control system, utilising a building block principle. The T4PLUS and T8PLUS are intelligent 2-door controllers of 4000 and 8000 card capacity respectively. The Tower Plus units are compatible with existing T4000 and T8000 units. Individual units are linked together using an RS485 two wire communications buss. Up to 63 units may be installed on the same network allowing control of up to 126 doors.

Programming is extremely simple by the use of a hand held programmer (TPROG) with simple yes/no commands and text LCD display. The TPROG can be used to program a single Tower unit or program a complete network from any Tower location. TPROG may also be used for viewing system status, alarms and the complete system data base without the need for a central PC.

Tower distributed intelligence provides high reliability due to each Tower Plus unit storing the full system data base for the total network. Data is automatically transferred to any other Tower and in the event of memory failure the unit will automatically refresh from another Tower Plus on the network. This also results in instant response to alarms and card transactions because all the decisions are made locally and not at a remote PC.

Automatic Timezone controlled unlocking of 2 groups of specified doors is included. This useful feature may also be card activated.

All major reader types such as Magnetic Stripe, Wiegand, Barcode and Proximity may be used with Tower offering the total solution to access control applications. Card, card and code, code only configurations are all possible. A messaging facility can be provided at the keypads allowing the PC operator to pass information to a specified card holder.

The built-in serial port allows connection to a local printer, host computer or up to four Building Management System expansion units – each BMS unit providing an additional 24 alarm inputs and 16 control outputs. The same unit also provides lift control.

Windows software is available, allowing total control of the network from a PC with the advantage of name files, card holder, alarm and transaction storage for audit purposes.
